Uterine cyst in female dogs: causes, symptoms and treatment

Uterine cysts can appear in female dogs, usually not spayed. They require urgent treatment. They can be the cause of a pyometra, which is an accumulation of pus in the uterus. If left untreated, the consequences can be serious. Let's take a look at this inflammation of the uterus in the female dog and take it very seriously.

Uterine cyst at the origin of pyometra: symptoms that should alert

A hormonal disease, the glandulocystic hyperplasia of the uterus, can be deplored in many female dogs. It occurs as a result of the development of several cysts and a thickening of the uterine lining called the endometrium. Complications are serious as the disease progresses, especially if treatment is not started early enough.

Pyometra is an inflammation of the uterus that can in some cases be due to the evolution of glandular cystic hyperplasia. Older and middle-aged unspayed female dogs are more prone to pyometra, but this uterine inflammation can also develop in young female dogs. In this case, it is rather favored by a hormonal treatment that can be administered :
  • either to interrupt a gestation in progress: the female dog receives an injection of estrogens,
  • or to postpone the heat period.
The pyometra appears quite quickly after the end of the treatment.

This uterine inflammation is favored by cysts appearing on the endometrium. They form pockets containing pus. The uterus is then more vulnerable to pathogenic bacteria that are likely to colonize it, especially during periods of heat during which the female loses blood. Note that uterine cysts are not the only cause of pyometra.

The symptoms that should alert the owner are the following:
  • The vulva is swollen,
  • Vulvar discharge is more or less important,
  • The female dog may appear weakened,
  • The males are attracted to the female when she is not in heat.

Pyometra: treatment

It is important not to wait to consult a doctor so that the pathogenic bacteria are completely eliminated. The accumulation of pus in the uterus warrants urgent care. When all the pus is removed, the veterinarian will administer a long-term antibiotic treatment to cure the bacterial infection. But in many cases, the female dog is so weakened that even intensive treatment cannot save her life.

The only effective way to treat a female dog with pyometra is surgery to remove the ovaries and uterus. The hospital stay lasts at least 48 hours. However, it can be prolonged in case of peritonitis or bleeding, which are possible complications.

After an ovariectomy, it is common to notice side effects, such as an increase in appetite, weight gain, slight incontinence in one out of ten females, which manifests itself as urine leakage, and a change in the quality of the coat, which is more visible in long-haired breeds.

Uterine cyst and inflammation: dog breeds most at risk for pyometra

Female dogs that are more frequently susceptible to pyometra belong to the following dog breeds:
  • Golden Retriever,
  • Rottweiler,
  • English Cocker Spaniel,
  • Long-haired Collie,
  • Cavalier King Charles Spaniel.
But this does not mean that other breeds are completely protected against this purulent inflammation of the uterus.

To prevent a uterine cyst from degenerating, it is very important to visit the veterinarian on a regular basis to have the animal checked. At the same time, it is recommended to have your female dog spayed as soon as possible. Sterilization is a surgical procedure that is very frequently performed to preserve the health of your pet. Moreover, it can be covered by mutual health insurance companies for pets.
